FIG. 1 shows a back perspective view of an embodiment of a boat havingan outboard motor equipped with a pair of stabilizer plates and a pairof rudders according to this disclosure. In particular, a boat 100includes a hull 102 having a bow 104 and a stern 106. The boat 100includes a starboard side 108 and a port side 110, each spanning betweenthe bow 104 and the stern 106. The boat 100 includes a pair of opposingcleats 112 secured to the hull 102 between the bow 104 and the stern106, such as via fastening, clamping, mating, or other ways. The boat100 includes a cockpit 114 between the bow 104 and the stern 106, withthe cockpit 114 containing an instrument panel equipped with a steeringwheel 116 and a set of input devices 118, such as buttons, levers,dials, or others, whether analog or digital. The boat 100 includes atransom 120 at the stern 106, where the transom 120 spans between thestarboard side 108 and the port side 110. The boat 100 includes anoutboard motor 122 that is secured to the transom 120, such as viafastening, clamping, mating, or other ways. The outboard motor 122 iscontrolled via the instrument panel. For example, the instrument panelcan control propulsion, such as via the set of input devices 118, orsteering, such as via the steering wheel 116, of the boat 100 via theoutboard motor 122.

The outboard motor 122 includes a powerhead section 124, a midsection128, and a lower unit 130, with the midsection 128 being securelyinterposed between the powerhead section 124 and the lower unit 130. Thepowerhead section 124 contains a power source, such as an internalcombustion engine, which may be gasoline based, or an electric motor,which may be battery based. The powerhead section 124 includes a cowling126 enclosing the power source and detachably attached to the powerheadsection 124, such as via mating, fastening, clamping, or other ways. Themidsection 128 contains a shaft which is mechanically linked, such asvia a set of meshing gears, to the power source such that the shaft isable to rotate when the power source is driven. The lower unit 130includes a jet drive containing an intake portion 138, an impeller, anda jet outlet portion 132. The impeller is rigidly mounted onto theshaft, such as within or in proximity of the jet outlet portion 132. Thejet outlet portion 132 includes a nozzle 140, which is circular inshape, but may be of any closed shape, such as triangular, oval, square,rectangular, parallelogramic, trapezoidal, pentagonal, octagonal, orothers. The jet outlet portion 132 is directionally adjustable along aplane generally parallel to the midsection 128, such as a verticalplane, such as up and down, although lateral adjustment is possible,such as along a plane generally perpendicular to the midsection 128,such as a horizontal plane, such as toward the starboard side 108 or theport side 110. The lower unit 130 includes a pair of stabilizer plates134 and a pair of rudders 136. The stabilizer plates 134 outwardlyextend from the lower unit 130, whether identical to or different fromeach other in direction or orientation, such as in T-shape manners. Therudders 136 extend from the stabilizer plates 134, whether identical toor different from each other in direction or orientation, such asgenerally perpendicularly. As the power source (in the powerhead section124) drives the impeller (in the lower unit 130) through the shaft (inthe midsection 128), water is (1) input, such as via negative pressure,into the intake portion 138, (2) directed toward the impeller such thatthe impeller impels the water toward the jet outlet portion 132, and (3)output through the nozzle 140 such that the boat 100 is propelled in adirection opposite the output of the water. Note that although theoutboard motor 122 is jet drive based, in other embodiments, theoutboard motor 122 is propeller based, whether additional to oralternative to the jet drive.

FIG. 2 shows a back perspective view of an embodiment of a lower unit ofan outboard motor equipped with a pair of stabilizer plates and a pairof rudders according to this disclosure. FIG. 3 shows a lateral profileview of an embodiment of an outboard motor equipped with a pair ofstabilizer plates and a pair of rudders according to this disclosure. Inparticular, each of the stabilizer plates 134 includes a first endportion 148 and a second end portion 150, where the first end portion148 and the second end portion 150 oppose each other and a respectiverudder 136 extends from that stabilizer plate 134 between the first endportion 148 and the second end portion 150. The first end portion 148 isproximal to the jet outlet portion 132 and the second end portion 150 isdistal to the jet outlet portion 132. Although the stabilizer plates 134are distinct L-shaped units, the stabilizer plates 134 can be in asingle unitary unit, such as a U-shaped or C-shaped unit. At least oneof the stabilizer plates 134 can include any rigid or flexible, solid orperforated material suitable for water use, such as plastic, metal,rubber, wood, or others. Although the stabilizer plates 134 areidentical to each other in structure, material, shape, or othercharacteristics, the stabilizer plates 134 can differ from each other instructure, material, shape, or other characteristics.

Each of the stabilizer plates 134 includes a set of bores 142 boredbetween the first end portion 148 and the second end portion 150.Although the set of bores 142 includes three bores, any number of boresmay be used, such as at least one bore. Although the set of bores 142extends rectilinearly, any non-linear, such as a closed shape, orlinear, such as sinusoidal, arcuate, or others, extension is possible.Although the set of bores 142 includes three identically structuredbores, any structure of bores or structure combination of bores may beused, whether identical to or different from each other in variousmeasureable characteristics, such as in diameter, depth, shape, innersurface texture, threading (male/female), or others.

Although each of the rudders 136 is shaped as a right trapezoid, anytrapezoidal structure is possible, such as acute, obtuse, or others.Likewise, non-trapezoidal structure is possible as well, such as arectangle, a square, a semi-circle/oval, a triangle, or others. Althougheach of the rudders 136 is cross-sectionally wedge-shaped, othercross-sectional shapes are possible, such as rectangular, circular,oval, or others. At least one of the rudders 136 can include any rigidor flexible, solid or perforated material suitable for water use, suchas plastic, metal, rubber, wood, or others, whether identical to ordifferent from the material included in at least one of the stabilizerplates 134. Although the rudders 136 are identical to each other instructure, material, shape, symmetry, or other characteristics, therudders 136 can differ from each other in structure, material, shape,symmetry, or other characteristics.

Each of the rudders 136 includes a base 152, a pair of lateral sides154, a leading edge portion 156, and a back portion 158, where the base152 spans between the leading edge portion 156 and the back portion 158and where the pair of lateral sides 154 generally perpendicularly extendfrom the base 152 and the back portion 158, although generalnon-perpendicular extension is possible, such as acute or obtuse. Theleading edge portion 156 is outwardly tapered towards the pair oflateral sides 154.

The base 152 includes a set of wells 146 formed between the pair oflateral sides 154 and between the leading edge portion 156 and the backportion 158. Although the set of wells 146 includes three wells, anynumber of wells may be used, such as at least one well. Although the setof wells 146 extends rectilinearly, any non-linear, such as a closedshape, or linear, such as sinusoidal, arcuate, or others, extension ispossible. Although the set of wells 146 includes three identicallystructured wells, any structure of wells or structure combination ofwells may be used, whether identical to or different from each other invarious measureable characteristics, such as in diameter, depth, shape,inner surface texture, threading (male/female), or others.

The rudders 136 are secured to the stabilizer plates 134 via a set offasteners 144, whether rigid or flexible, such as screws or bolts, whichmay include metal, plastic, rubber, wood, or other suitable materials.Although the set of fasteners 144 includes three fasteners, any numberof fasteners may be used, such as at least one fastener. Although theset of fasteners 144 includes three identically structured fasteners,any structure of fasteners or structure combination of fasteners may beused, whether identical to or different from each other in variousmeasureable characteristics, such as in diameter, depth, shape, outersurface texture, threading (male/female), or others. Note that therudders 136 avoid extending vertically lower than the intake portion138, such as to allow for shallow water operation, although extendingpast the intake portion 138 is possible, such as for non-shallow wateroperation.

Although the rudders 136 are secured to the stabilizer plates 134 viathe set of fasteners 144, the rudders 136 can be secured to thestabilizer plates 134 in other ways. For example, some of such waysinclude clamping, mating, interlocking, adhering, magnetizing,hook-and-looping, sowing, nailing, stitching, welding, casting, or anyothers. Additionally, the rudders 136 and the stabilizer plates 134 canalso be unitary, such as a single monolithic piece.

Although the rudders 136 and the stabilizer plates 134 are in T-shaperelationships, such as generally perpendicular, other relationships arepossible, such as generally non-perpendicular, such as acute or obtuse.Note that at least one of the rudders 136 can extend from at least oneof the stabilizer plates 134 from any point between the first endportion 148 and the second end portion 150, such as within 9/10 of thatdistance, within 8/10 of that distance, within 7/10 of that distance,within 6/10 of that distance, within 5/10 of that distance, within 4/10of that distance, within 3/10 of that distance, within 2/10 of thatdistance, or within 1/10 of that distance, as measured between the firstend portion 148 and the second end portion 150. For example, if thatdistance is about 10 inches, then that rudder 136 can be secured at anypoint within those 10 inches, such as at within 9 inches from the firstend portion 148 or within 5 inches from the second end portion 150 orany others, inclusively. In some embodiments, an advantage to securingthat rudder 136 between the first end portion 148 and the second endportion 150, such as within ¾ or ⅔ of that distance, is that suchstructure causes less cavitation, which causes the boat 100 to rockside-to-side by air bubbles trapped under the boat 100, as produced bythe water output of the outboard motor 122. Likewise, such configurationcan also control the boat 100 at any speed, while effectively reducingsideways or lateral slide and water skidding while turning the boat 100.However, in some embodiments, that rudder 136 can be secured at thefirst end portion 148 or at the second end portion 150.

In one mode of operation, a user can access the outboard motor 122including the jet outlet portion 132 and the stabilizer plate 134, wherethe stabilizer plate 134 includes the first end portion 148 and thesecond end portion 150, where the first end portion 148 is proximal tothe jet outlet portion 132, where the second end portion 150 is distalto the jet outlet portion 132; and couple the rudder 136 to thestabilizer plate 134 between the first end portion 148 and the secondend portion 150.

In one mode of operation, a user can operate the boat 100 with theoutboard motor 122 where the outboard motor 122 is equipped with the jetoutlet portion 132 and the stabilizer plate 134, where the stabilizerplate 134 includes the first end portion 148 and the second end portion150, where the first end portion 148 is proximal to the jet outletportion 132, where the second end portion 150 is distal to the jetoutlet portion 132, and the rudder 136 extends from the stabilizer plate134 between the first end portion 148 and the second end portion 150.

FIG. 4 shows a lateral profile view of an embodiment of an outboardmotor equipped with a pair of stabilizer plates and a pair of rudderswhere the stabilizer plates can rotate with respect to a lower unit ofthe outboard motor according to this disclosure. In particular, theoutboard motor 122 includes a pair of shafts 160 rigidly secured to thelower unit 130 on opposing sides thereof in opposing directions fromeach other, while extending along the transom 120, such that the shafts160 can be independently or dependently, synchronously or asynchronouslydriven by the power source enclosed via the cowling 126 andindependently or dependently, synchronously or asynchronouslycontrollably rotated about their respective axes, such as within apredefined rotation range, such as between about 0 and about 90 degrees,although higher amounts are possible, such as about 360 degrees, orfreely rotate. The shafts 160 can avoid extending out of the lower unit130 or extend out of the lower unit 130. The shafts 160 can be rigid orflexible, solid or perforated and include any suitable material, such asplastic, metal, rubber, wood, or others. The stabilizer plates 134 arerigidly secured to the shafts 160 at any points thereof, such asexternal to the lower unit 130. As such, when the shafts 160controllably rotate about their axes, the stabilizer plates 134 aremoved clockwise or counterclockwise, such as up or down, as illustratedin FIG. 4.

Note that this controlled movement is independently or dependently,synchronously or asynchronously controlled at the instrument panel, suchas via the set of input devices 118, such as via a set of hydraulicequipment, a set of pneumatic equipment, a set of cables, a set ofmeshing gears, or any other actuation technology within the boat 100 andwithin the outboard motor 122 and can be manually powered or, as notedabove, independently or dependently, synchronously or asynchronouslypowered via the power source enclosed via the cowling 126. Further, notethat this controlled movement can be manually synchronously orasynchronously controlled, such as via the set of input devices 118, orautomatically synchronously or asynchronously controlled, such as aprocessing circuit, whether local to or remote from the boat 100 or theoutboard motor 122, such as based on a set of data feeds from a set ofinput devices, whether local to or remote from the boat 100 or theoutboard motor 122, such as a camera, a sonar, a radar, an ultrasonicsensor, a laser, or others. In some embodiments, a single shaft 160 isused, where the stabilizer plates 134 are secured thereto and the singleshaft 160 spans laterally along the transom 120 through the lower unit130 and extends outside of the lower unit 130 on both sides in opposingdirections to which the stabilizer plates 134 are attached, which may beremovably. In some embodiments, the rudders 136 extend from the shaft(s)160, without the stabilizer plates 134, such as assembled, such as viafastening, mating, adhering, or others, including any assemblingmethodology disclosed herewith, or unitary therewith.

FIG. 5 shows a back profile view of an embodiment of an outboard motorequipped with a pair of stabilizer plates and a pair of rudders wherethe stabilizer plates can flap with respect to a lower unit of theoutboard motor according to this disclosure. In particular, the outboardmotor 122 includes a pair of telescoping pneumatic piston-cylinderassemblies 162, each spanning between the midsection 128 and thestabilizer plates 134, although a pair of pivoting mechanical joints ispossible, whether additional or alternative thereto, such as where amechanical joint includes a plurality of bars pivotally attached to eachother for inward/outward folding, such as via a pin, a screw, or abolt/nut. The assemblies 162 oppose each other with the midsection 128positioned therebetween. The assemblies 162 are independently ordependently, synchronously or asynchronously driven via the power sourceenclosed via the cowling 126 and can be independently or dependently,synchronously or asynchronously controlled via the instrument panel,such as via the set of input devices 118.

The lower unit 130 includes a pair of lateral slots, such as verticallyor diagonally ovoid, rectangular, square, or any other closed shape. Thestabilizer plates 134 are attached to the lower unit 130 through suchslots such that the stabilizer plates 134 can flap toward the cowling126 or away from the cowling 126, whether in a clockwise orcounterclockwise direction, as the assemblies 162 controllably telescopeoutward and inward. Therefore, when the stabilizer plates 134controllably flap via the assemblies 162, the rudders 136 are movedclockwise or counterclockwise, such as up or down, as illustrated inFIG. 5.

In some embodiments, although the lower unit 130 includes the pair oflateral slots, as noted above, a single slot, such as within a wall, orno slot at all is possible, such as when the stabilizer plates 134 areexternally attached to the lower unit 130, such as when the stabilizerplates 134 together form a C-shape or a U-shape. For example, thestabilizer plates 134 can be attached to the lower unit 130 withoutusing such slots, such as via a pivoting or gear mechanism externallymounted on the lower unit 130. Likewise, note that other ways of pullingor pushing/dropping the stabilizer plates 134 are possible. For example,the stabilizer plates 134 can flap via a set of gears or pulley systemsinternal to the lower unit 130 or an electric motor securely housedwithin the lower unit 130.

Note that this controlled flapping movement is independently ordependently, synchronously or asynchronously controlled at theinstrument panel, such as via the set of input devices 118, such as viaa set of hydraulic equipment, a set of pneumatic equipment, a set ofcables, a set of meshing gears, or any other actuation technology withinthe boat 100 and within the outboard motor 122 and can be manuallypowered or, as noted above, independently or dependently, synchronouslyor asynchronously powered via the power source enclosed via the cowling126. Further, note that this controlled movement can be manuallysynchronously or asynchronously controlled, such as via the set of inputdevices 118, or automatically synchronously or asynchronouslycontrolled, such as a processing circuit, whether local to or remotefrom the boat 100 or the outboard motor 122, such as based on a set ofdata feeds from a set of input devices, whether local to or remote fromthe boat 100 or the outboard motor 122, such as a camera, a sonar, aradar, an ultrasonic sensor, a laser, or others.

FIGS. 6A-6B show a back profile view of an embodiment of an outboardmotor equipped with a pair of stabilizer plates and a pair of rudderswhere the rudders are able to rotate with respect to the stabilizerplates according to this disclosure. In particular, the lower unit 130includes a pair of shafts rotationally attached to the stabilizer plates134, such as perpendicularly or non-perpendicularly, such as acute orobtuse, and rigidly attached to the rudders 136 such that when theshafts controllably rotate about their axes, the rudders 136 are rotatedthereby. The shafts can be independently or dependently, synchronouslyor asynchronously driven by the power source enclosed via the cowling126 and independently or dependently, synchronously or asynchronouslycontrollably rotated about their respective axes, such as within apredefined rotation range, such as between about 0 and about 90 degrees,although higher amounts are possible, such as about 360 degrees, orfreely rotate.
